Fedora doesn't offer a vulkan-intel package. I have mesa-vulkan-drivers 21.3.8-2, and xorg-x11-drv-drv-intel 2.99.917-51.20200205.
Unfortunately, everything looks like Intel HD 4000 is not supporting Vulkan 1.2 on Linux. Sorry for the inconvenience.
I'll try to do more research about your setup and will let you know about the results.
Ok, thank you!
